We currently live in a home we lease from a landlord living in Florida (we live in north carolina). We have been in the home for nearly 18 months (releasing after one year and signing another year lease). Our lease requires we mail the rent by the first of each month, no later without a 45.00 late fee. On two occasions now (this month being the 2nd in 18 months, the landlord has not received our rent in the mail after about the 6th of the month and begins to call, making harrassing statements, etc. However, has never served us any written demand of payment once the mail is considered too late by their standards. The lease does not make allowance for a 5-day late period. The first time this happened we had actually postmarked the rent on December 31, for Jan 2005's rent. By the 7th of January they had not received it and called us, demanding we wire the money immediately. Come to find out, after I gave them my certified mailing receipt number, the mail had been delivered to their post office and had been sitting there several days. Now this has happened again, only this time they have an attorney calling on their behalf as she now handles the rental payments, etc. Once I've mailed the payment, it is out of my hands as I cannot control the speed of the mail. Can I stop the harrassing phone calls? They are stressful and these people are crass and very rude. Other than these two incidents, we've been consistently prompt and I always mail it certified for proof. Help?
